Fluid mechanics is the study of fluids (liquids and gases) in motion and at rest. It's a vast field that encompasses many aspects of fluid behavior, including:
Key Concepts:
* Fluid Properties: Density, viscosity, compressibility, surface tension
* Fluid Statics: Pressure, buoyancy, Archimedes' principle
* Fluid Dynamics: Flow patterns, velocity, acceleration, pressure gradients, drag, lift, turbulence
* Conservation Laws: Mass, momentum, and energy conservation
